Video surveillance is widely used in establishing the societal security network. In this paper, intrusion detection based on visual information acquired by static camera is proposed. Proposed approach uses background model constructed by approximated median filter(AMF) to find a foreground candidate, and detected object is calculated by analyzing motion information. Motion detection is determined by the relative size of 2D object in RGB space, finally, the threshold value for detecting object is determined by heuristic method. Experimental results showed that the performance of intrusion detection is better one when the spatio-temporal candidate informations change abruptly.

Food spoilage by fungi is responsible for considerable food waste and economical losses. Among the food products, fermented dairy products are susceptible to deterioration due to the growth of fungi, which are resistant to low pH and can proliferate at low storage temperatures. For controlling fungal growth in dairy products, potassium sorbate and natamycin are the main preservatives used, and natamycin is approved by most countries for use in cheese surface treatment. However, a strong societal demand for less processed and preservative-free food has emerged. In the dairy products, lactic acid bacteria (LAB) are naturally present or used as cultures and play a key role in the fermentation process. Fermentation is a natural preservation technique that improves food safety, nutritional value, and specific organoleptic features. Production of organic acids is one of the main features of the LAB used for outcompeting organisms that cause spoilage, although other mechanisms such as antifungal peptides obtained from the cleavage of food proteins and competition for nutrients also play a role. More studies for better understanding these mechanisms are required to increase antifungal LAB available in the market.

Data innovation is at the core of the Fourth Industrial Revolution. While the catastrophic COVID-19 pandemic has accelerated the societal shift toward a data-driven society, the direction of overall data regulation remains unclear and data policy experts have yet to reach a consensus. This study identifies and examines the ideal regulator models of data-policy experts and suggests an appropriate method for developing policy in the data economy. To identify different typologies of data regulation, this study used Q methodology with 42 data policy experts, including public officers, researchers, entrepreneurs, and professors, and additional focus group interviews (FGIs) with six data policy experts. Using a Q survey, this study discerns four types of data policy regulators: proactive activists, neutral conservatives, pro-protection idealists, and pro-protection pragmatists. Based on the results of the analysis and FGIs, this study suggests three practical policy implications for framing a nation's data policy. It also discusses possibilities for exploring diverse methods of data industry regulation, underscoring the value of identifying regulatory issues in the data industry from a social science perspective.

This study intends to examine the changes found in the unit floor plans of the apartments built in Beijing from 1979 to 2018. For the 3 - bedroom type apartments, 40 unit floor plans were collected, and the changes of integration values of each space were analyzed periodically in four phases. The unit floor plans are analyzed in the context of the Space Syntax Model and compared to the lifestyle and societal changes in China. The results of the study indicate the followings: As time went by, the living room and the dining room were separated from each other with the increasing area of the apartment unit floor plans. The function of the integrated living room was dispersed, and the integration of the living room and the dining room decreased with the change of time. In the third phase, the dining room occupied the center of the unit floor plans with the highest integration value; Chinese people prefer to place the kitchen in the relatively deep place in order to prevent oil and smoke caused by their cooking habits like stir-fry; The privacy of the master bedroom has been strengthened.

Vaccine diplomacy is a manifestation of competition for political influence among great powers amidst the Covid-19 pandemic's blatant illustration of ineluctable interdependency across the global community. The reinforcement of trends bolstering global polity construction intensify concomitantly with nationalist populist value and attitude expressions increasing political polarization. The interdependency graphically illustrated in the Cold War-era's mutual assured destruction incentivized competition into indirect competitive intervention in the internal politics of third actors. Indirect international influence contestations included extended, de facto challenge competitions to generate soft power on behalf of the victor, e.g., the space race. The Covid-19 pandemic has intensified this competition to offer alternative development models while intense domestic political polarization undermines the mobilizational capacities for achieving sustainable development. In contrast to multinational and multiethnic states, nation states have an inherent mobilizational advantage because of the enhanced control capabilities available to the authorities without emphasizing coercion. Control through Gramscian hegemonic mechanisms is more readily feasible in nation states through the greater feasibility of commodification of social relations by states authorities regulating and channeling social competition to encourage social mobility and creativity. The regulation of the so-called private sector serves to manage and contain social competition while channeling it to develop the institutional capacities for control and allocation of developing societal human resources. It enhances developed state control mechanisms and international influence capacities. The appeal of offers of aid and assistance to the so-called developing world becomes ever more urgent amidst Anthropocene crises including its most recent, current Covid-19 pandemic disaster.

Expectations for artificial intelligence technology are increasing, and its utility value is growing, leading to active use in the public sector. The use of artificial intelligence technology in the public sector has a positive impact on aspects such as improving public work efficiency and service quality, enhancing transparency and reliability, and contributing to the development of technology and industries. For these reasons, major countries including Korea are actively developing and using artificial intelligence in the public sector. However, artificial intelligence also presents issues such as bias, inequality, and infringement of individuals' right to self-determination, which are evident even in its utilization in the public sector. Especially the use of artificial intelligence technology in the public sector has significant societal implications, as well as direct implications on limiting and infringing upon the rights of citizens. Therefore, careful consideration is necessary in the introduction and utilization of such technology. This paper comprehensively examines the legal issues that require consideration regarding the introduction of artificial intelligence in the public sector. Methodological discussions that can minimize the risks that may arise from artificial intelligence and maximize the utility of technology were proposed in each process and step of introduction.

This study was to evaluate economic impact of a comprehensive pharmaceutical care intervention provided by community pharmacists on drug-related morbidity and mortality in the elderly population, in a societal perspective. Clinical outcomes of pharmaceutical care included compliance increase, inappropriate medication discontinuation, and subsequent drug-related morbidity and mortality reduction. Economic outcomes included cost savings from direct medical costs reduction such as medication and healthcare resource utilization. Input costs for pharmaceutical care included pharmacist time and computerized prescription review supporting program costs. Model parameters of outcomes were derived from published literatures, and costs were from literatures and health insurance statistical data in Korea. Annual costs and benefits were estimated in the year 2005. Current usual care and standardized pharmaceutical care required 0.3 and 2.0 hours per year respectively, for elderly outpatient using average 4.4 prescription drugs per visit and average annual frequency of 17.8 pharmacy visits. Comprehensive pharmaceutical care provided to overall elderly outpatients at community pharmacies would have cost of \74,994 mil. and benefit of \357,002 mil. per year. Benefit:cost ratio was 4.8:1 and net benefit was \282,008 mil/year. It was corresponded to net benefit of \73,816/year for individual elderly patient. In addition, pharmaceutical care was estimated to reduce 1,531 drug-related deaths/year. Conclusively this study, a first attempt in Korea to evaluate an economic value of pharmaceutical care at community pharmacies, proved that it was a cost-effective intervention having significant economic benefit.

On the threshold of year 2000, the elderly account for more than 7% of the whole population in Korea, which means that the nation is greeting welcoming an aging society. Accordingly, it is expected that silver businesses and services targeted at the silver generation will prosper with "silver advertising design" becoming active. Under such circumstances, this study was aimed at reviewing the recent silver marketing advertisements in terms of their cultural and moral implications, and thereby, redefining and reestablishing the status of silver consumers to help them find their identity, aware of marketing activities and therewith, establish their "consumer sovereignty". This study consists in large of 5 chapters. The introduction parr describes background, purpose, method and scope of the study. The first chapter reviews the silver marketing theories. The second chapter classifies the silver marketing advertisement positioning of four style - upper classes style, effloresce progress style, self- sufficiency style, dependent style - and reviews the expression strategy of each positioning. The third chapter examines the domestic conditions of silver marketing advertisements for each positioning type classified. The fourth chapter designs the ′creative′of silver marketing advertisements and suggests the methods thereof. The analysis of ′creative′was tested in terms of graphic gestaltung, and how the sliver marketing advertisement positioning should be discerned depending on silver generation consumer′s characteristics was discussed. The fifth chapter puts forwards the suggestions for the ′creative′ strategies to enhance the effects of the silver marketing advertisements, based on the preceding discussions. In addition, the Perspective into the keyword of 21 st century or "silver design" is discussed, together with the limitations of this study. It is hoped that this stuffy will be conducive to our efforts to face the upcoming′age\ulcorner society′more effectively. To this end, this study discusses the "silver advertising design" in light of ′societal concepts′and ′customer-oriented value′, and thus, explores some creative presentation strategies whereby individual companies interests and social or public interests can be compromised through ′creative activities′ and ′equal-value consumerism′ for an ultimately effective management strategies for silver businesses and services.

Sustainability science is an emerging transdisciplinary research which necessitates not only the communication and collaboration of scientists, practitioners and stakeholders from different disciplines and interests, but also the paradigm shift from deterministic and reductionist approaches to the old basic. Ecological-societal systems (ESS) are co-evolving complex systems having many interacting parts (or agents) whose random interactions at local scale give rise to spontaneous emerging order at global scale (i.e., self-organization). Here, the flows of energy, matter and information between the systems and their surroundings play a key role. We introduce a conceptual framework for such continually morphing dynamical systems, i.e. self-organizing hierarchical open systems (SOHOs). To understand the structure and functionality of SOHOs, we revisit the two fundamental laws of physics. Re-interpretation of these principles helps understand the destiny and better path toward sustainability, and how to reconcile ecosystem integrity with societal vision and value. We then integrate the so-called visioneering (V) framework with that of SOHOs as feedback/feedforward loops so that 'a nudged self-organization' may guide systems' agents to work together toward sustainable ESS. Finally, example is given with newly endorsed Sustainable Development Goals (SDG) Lab (i.e., 'Rural systems visioneering') by Future Earth, which is now underway in rural villages in Tanzania.
